Abstract
A grease plug adapted to fit into a cross hole in communication with a through-greasing passage and to reduce the effective cross-sectional area of the cross hole. The grease plug comprises (1) a generally cylindrical plug portion having at least one grease passage extending generally axially thereof and (2) a generally hook-shaped mounting portion which functions as a snap lock to retain the plug portion in the cross hole. In one embodiment, the mounting portion itself is long enough to bear against the inner surface of the through-greasing passage to prevent the grease plug from being lost therein; in another embodiment, a spacing portion is provided on the bottom of the mounting portion, and the spacing portion bears against the inner surface of the through-greasing passage. The grease passage can have various shapes.
